Hello all you jeep liberty 2005 and 2006 diesel crd
This is what's going on with your jeep at around 100,000 miles + - 20,000. You will be blowing black smoke bad and what ever sensor, egr ect you change it will not work. Your exhaust cam and rockers will be DONE. If your lucky IOU won't cook a piston before you figure it out. The mobile oil that is from jeep specs is bullpoop it's not heavy enough you must go heavier. And get the computer flashed it's the only why. Trust me I just sunk 4000$ into it IDparts.com have great prices on it while your in there you should do the water pump ting belt ( mine was still ok) as most are. My mech in Windsor ont canada Windsor gas and diesel is a expert at these after one there was 4 more out side all with the same miles and problem. Don't listen to the dealer. If they even work on it 95% wouldn't touch it. The flash is from Detoit boy who worked on the jeep project. It will bypass emissions. It's the only way or next 100,000 do it again just to let you know.
